Fed up with Vodacom

Very unhappy with Vodacom....endless stuggles since March/April this year... Did upgrade on a phone but it came out too much per month. Cancelled upgrade. Had to wait until I could do upgrade. Changed flexi 175 to flexi 125. I was told it is fine and done. Vodacom app still showed same old package. After nearly two weeks had to find out that upgrade could not be completed as back office did cancel the upgrade but never changed the date...so I showed that upgrade can be done in two years time... Had to wait like a week for that date to be changed. Then upgrade could be done. I was told will have flexii 125 with 500 mb... I said no there is already a 2 gig for every month and asked what else can be offered? I accepted then the once off 20 gig data valid for one month. I was told that can only be loaded 1 June. I was also told in May with the upgrade that rhe handset fee will be payable for the last time with my debit order for 1 June and that my new bill for the upgrade will be like R99 pm for the R125 airtime and R18 for the 2 gig data pm. So total bill pm will be from after 1 June like R116/R118. BUT NOW: still no 20 gig once of data and the handset fee is still there. When I called today, u was told there is nothing showing 20 gig data...i said in May on the phone I was offered 500 mb pm but sais there is 2 gig pm already and cant I have the 20 git once off for 30 days - the same I got for my phone the previous month when I upgraded. I was told because I am an important client, I can have it but it will only be loaded 1 June and that I found strange as when I upgraded the 20 gig reflected wirhin 24 hours. Today to my horror my app showed only the normal 2 gig and no 20 gig once off and even showing still the handset fee Vodacom said will be payable for the last time 1 June on my debit order and as I already mentioned that from like now my bill will be in total only like r116 or r118 pm.
